Abstract
A constant speed travel control system uses a time period Q which is set such that, if a motor of the actuator is not locked but normally rotated, actuator opening becomes almost certainly fully closed within that time period with the result that a first limit switch is made open. If the motor is normal, the processing operation proceeds to a normal constant speed travel control by which an electric current to the motor ceases and 'motor open' condition is detected. When no 'motor open' state is detected, even after the elapse of the time period Q, under the condition that the vehicle speed is higher than a reference speed, a determination that the motor is in the locked condition is made and the operation proceeds to a speed control cancellation process.
